There are tons of them working in the restaurant industry. They are filthy animals. Back where they come from everyone has built up a tolerance to eating food mixed with human waste - so why should they care about washing their hands?
That’s one reason I don’t like eating out and avoid it when I can.
First thing you do at a restaurant:
Check the washroom for soap and towels.
If no way for employees to wash hands, find another place to dine.
Basic hygiene 101.
